I like the new navigators, but I'm finding there's a glitch where the Selected state doesn't change when users select a different navigator! They only correctly update when a person hovers the old bookmark, which is incredibly problematic for mobile layouts.
In the example below, the % Donut bookmark is active, but I then select the $ Donut bookmark. Both navigators remain highlighted despite $ Donut being active. When I mouse over % Donut, then it updates.
